Reliable and robust methods of extreme value based hurricane surge prediction, such as the Joint Probability Method (JPM), are critical in the coastal engineering profession. The JPM has become the preferred surge hazard assessment method in the United States; however, it has a high computational cost: one location can require hundreds of simulated storms, and more than ten thousand computational hours to complete. Optimal sampling methods that use physics based surge response functions (SRFs), can reduce the required number of simulations. This study extends the development of SRFs to bay interior locations at Panama City, Florida. Mean SRF root-mean-square (RMS) errors for open coast and bay interior locations were 0.34 m and 0.37 m, respectively; comparable to expected ADCIRC model errors (~0.3 m—0.5 m). Average uncertainty increases from open coast and bay SRFs were 10% and 12%, respectively. Long-term climate trends, such as rising sea levels, introduce nonstationarity into the simulated and historical surge datasets. A common approach to estimating total flood elevations is to take the sum of projected sea-level rise (SLR) and present day surge (static approach); however, this does not account for dynamic SLR effects on surge generation. This study demonstrates that SLR has a significant dynamic effect on surge in the Panama City area, and that total flood elevations, with respect to changes in SLR, are poorly characterized as static increases. A simple adjustment relating total flood elevation to present day conditions is proposed. Uncertainty contributions from these SLR adjustments are shown to be reasonable for surge hazard assessments. / Master of Science

Wind shear negatively impacts tropical cyclone (TC) intensity by disrupting the TC vortex and introducing lower equivalent potential temperature (θe) air, weakening the core. However, the ocean, a source of heat, aids in replenishing low θe boundary layer air, mitigating shear-induced ventilation effects. Favorable oceanic conditions, like higher sea-surface temperatures (SST), prevail in storm-relative motion quadrants not yet influenced by the TC. The interaction between storm-relative (e.g., SST) and shear-relative (e.g., ventilation) frameworks remains unclear. I propose an optimal overlap of shear-relative and motion-relative storm quadrants, where shear-induced weakening is minimized due to enhanced boundary layer recovery in a favorable ocean environment. This study presents a novel dataset comprising of co-located aircraft expendable bathythermographs (AXBT) and dropsondes from TROPIC and TC-DROPS datasets. Statistical analyses reveal air-sea correlations that cause up-shear and front-storm quadrant overlaps to be most beneficial to TC health, with investigation into the physical mechanisms driving these relationships.

This research focuses upon cases wherein post]disaster housing assistance was affected by tenure insecurity. In the case of post]Katrina New Orleans, the Road Home, which provided monies for rebuilding, faced difficulties in allocating its aid because of heirship titles, a form of tenure insecurity to which the United States has often been misconceived as immune. In the case of post]Hurricane Mitch in Tegucigalpa, a post]disaster housing relocation program struggled to find lands in an urban land market with pervasive insecurity

Northeastern and mid-Atlantic United States are understudied from the perspective of hurricane vulnerability. In an attempt to fill this gap in research, this dissertation attempted to assess the hurricane vulnerability of the northeastern and mid- Atlantic United States through the construction of a Composite Hurricane Vulnerability Index (CHVI) for 184 counties extending from Maine to Virginia. The CHVI was computed by incorporating indicators of human vulnerability and physical exposure. Human vulnerability was derived from demographic, social and economic characteristics whereas physical exposure was based on attributes of the natural and built up environments. The spatial distribution of the CHVI and its component indices were examined and analyzed to meet the research goals, which were a) to develop indices of human vulnerability, physical exposure and composite hurricane vulnerability for all counties; b) to assess vulnerability distribution in terms of population size, metropolitan status (metropolitan versus non metropolitan counties) and location (coastal versus inland counties); c) to identify the specific underlying causes of vulnerability; d) to identify the significant clusters and outliers of high vulnerability; and e) to examine overlaps between high human vulnerability and high physical exposure in the region. Results indicated high overall vulnerability for counties that were metropolitan and / or coastal. Vulnerability clusters and intersections pointed towards high vulnerability in the major cities along the northeastern megalopolis, in the Hampton Roads section of Virginia and in parts of Delmarva Peninsula. Evidence of relationship of population size, metropolitan status and location with vulnerability levels provides a new perspective to vulnerability assessment. / by Shivangi Prasad. / Thesis (Ph.D.)--Florida Atlantic University, 2013. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.

People with disabilities are likely to experience difficulties overcoming the impact of natural disasters. Few scholars have focused on this population's ability to recover and handle stress following a natural disaster. The purpose of this phenomenological study was to explore and describe coping strategies and resilience factors that people with physical or mental disabilities used in the aftermath of Hurricane Sandy. Resilience theory was used as the theoretical framework. Through face-to-face interviews, 10 persons with disabilities shared their experiences of coping and resilience. A lens of interpretative phenomenological analysis was used to identify emergent themes related to persons with disabilities' experiences of overcoming challenges and sustaining wellbeing in the aftermath of this natural disaster. According to study results, religion, recreation, and relaxation techniques were the main coping strategies used, and self-determination and independent skills were resilience factors that helped persons with disabilities remain positive and overcome challenges following the hurricane. Participants reported experiencing emotional reactions and identified the dislocation as the greatest stressor. The findings of this study have the potential to effect positive social change by informing stakeholders such as policymakers, community, and state agencies, and related professionals to help them recognize and address the health and psychological needs of persons with disabilities following a hurricane. Knowing which coping strategies and resilience factors persons with disabilities use to create awareness of the positive ways in which persons with disabilities manage the aftermath of this natural disaster.

In August and September of 2005, Hurricanes Katrina and Rita devastated the Gulf Coast with damages estimated at $85 billion. Hurricane Katrina was so devastating that the number of lives lost and injuries sustained is still being calculated. Hurricane Rita, which made landfall in the southwestern part of the Louisiana just a few weeks after Katrina, did not cause as much damage as Katrina but was devastating nonetheless. In both cases, two Louisiana community colleges, Nunez Community College and SOWELA Technical Community College, were damaged to the point that many doubted that either college would have a future. Both community colleges, however, continued classes and are in operation today. This study examines the actions of the institutional leadership at Nunez Community College and SOWELA Technical Community College in the aftermath of Hurricanes Katrina and Rita. A constructivist grounded theory approach was used to conduct case studies on each college. A substantive theory emerged from the findings explaining the resiliency of both institutions. / text
